SOLDERING-CLAMP.

Specification of Letters Patent.

Patented June 1913.

Application filed January 12, 1911. Serial No. 602,162.

To all whom it may concern.

Be it known that 1, Joan C. MCLAUGII- LIN, a citizen of the United States, residing of typewriting machines to the type bars; thedeviee facilitates the application of the solder, and insure a proper alinement of the type, so that theletters of the written page will be in line. It also operates as a surface gage, so that the face of the type will strike the paper squarely.

The object of the invention is to provide simple and efiective means for supporting the type with its face in the proper plane when it is being attached to the type bar, alining the type, and holding the type in the position in which it has been alined, until ,it has been secured by the solder.

is a perspective, showing m I have illustrated the age as used for securing the type to the type bars of an Underwood typewriter.

In the accompanying drawings, Figure 1 device as viewed from an'elevated position, showing a type-bar mounted for soldering, with the type soldered thereto. Fig. 2 is also a perspective of the parts near the point where the' type is supported, certain parts being broken away, and shown in cross section to illustrate more particularly the construction and operation of the alining means. Fig. 3 is a vertical transverse section taken through the device at the point where the type is supported and secured to the type bar, and this view further illustrates the means for insuring that all the types will have the same alinement. Fig. 1 is a.vertical section taken through a segment of the form used in the well known Underwood typewriter, and illustrating means for holding a type-bar temporarily in position to receive the type.

As illustrated in the accompanying drawings, my device comprises a base plate or table 5, upon which there is supported in any suitable manner a common horse shoe magnet 6 in an inverted position, having poles 7 and 8, to the upper ends of which a surface plate 9 may be secured by suitable studs or screws 10. The side edges of this plate project or overhang the edges of the poles 7 and 8, and at these points, to the plate 9, there is attached a gage block 11. This gage block is adapted to support a segment 12, laid flat upon it in the manner illustrated to facilitate the mounting of the type bars and the soldering operation. The base plate 5 may be provided with a suitable post 13, as shown, to assist in supporting the segment.

The surface plate 9 is formed with a transverse gap or slot 14, producing two sections or divisions of the plate, and this slot extends nearly across the plate. Small bonds or connecting bars 15 are left at the ends of the slot which connect the divisions of the plate. Extending nearly throughout the entire length of the gap 14, there is provided a filler or plug strip 16, which is composed of aluminum or some other non' magnetic metal or material. Aluminum is preferable because the solder ordinarily usedwill not adhere to it. The upper face of this filler is flush with the upper face of the surface plate.

At the rear edge of the surface plate 9, is

formed a transversely disposed shoulder or creased in thickness, so that this portion of 9 the block presents an elevated rest 20. the upper face of which is flush with the upper face of the aforesaid shoulder 17. in using the device, the segment 19, which is to.re ceive the type bars, is laid flat u ionthe rest 20 in a horizontal position with its type-bar guide 21 rojecting over the edge of the shoulder 12, and at the middle of the slot 14. Suitable marks or other means may be employed if desired for insuring proper alinement of the segment with rcspectto the gage-plate and gap. The segment is temporarily provided with a curved guide bar .22 which extends around over the radial type-bar slots 23 in the edge of the segment.

In Fig. 1 l illustrate a type bar24: set in position for securing the type 27 thereto. As shown in Fig. 4, this type bar is formed Withthe usual hook'25,"Which"engages the arcuate pivot rod 26, Which passes through the segment near the curved edge thereof. The slots 23 and the type bars are num- "b'ered correspondingl in mounting.- the to'the open slot "formed attheend 29 type bars they are applied on'e byone; eachin its correspondingly numbered slot 23 and hooked into the pivot rod 26 in t-he usual manner.

In order tohold-the type --bar in position f0-1"'soldering 'the "type 27 to it, a small coiled spring 28 is'suspended from-the bar 22' and detachably-connected above the'surface plate 9. v

The type 27 is provided on'its under-face With type characters 32, Which rest directly upon the snrfacepla-te 9, as="indicated"in Fig. 8. The upperside orback of the type isprovided With a longitudinal notch 33 in the usual manner, in which the 'head- 33 of the type bar is'received as-indicated'in Fig. 3. i

The magnet 6 inducesmagnetism'inthe surface'plate 9; and the' m'agnetic attraction holds the type standing orin anupright position-on the surface plate, and over-- comes any"tend'ency-of the type to move" or to tip over to oneside when touched. This insures a proper surface aliner'rient' of the type as Will presently 'appear.'-' In order to aline the type uniformly; the'g'age plate 18 is adjusted to such -a p'o'intthat'whenthe type is forced back \vitli"the" lovve1 case character against the edge of thegage' plate, the type will be in proper position to' strike the platen fairly in action. With'the'type in this position, itshonl'd b'e'soldere'd t o'ithe type bar by applying solder the *notch 33% in the usual manner.

After" one type has heen"a lined by "the gage-plate 18and secured to its proper type bar, by the solder, the'gage'plate IS'should be left in the same position, and the remain-f ing typesshould be held"aga'i'nst it successively in the samemanner as thatdescribed' In doing this, of course,"tlietype bars which have been soldered; should be thrownback out ofthewvayyso as to leav"th'e type har guide unobstructed.- The s ment ehouid he held fiXeduntiP-all the type-bars are atcached to it and soldered. This insuresunL remraiinemena i Tii' order 'toholdthe gage plate 18' iii posh 'tion, I may provide the-"shoulder 1Vtvitha small flat spring 34, which presses the gage plate against the surface plate as illustrated 'ihbstcleairlyih Fig. 3'. By nearly dividing the surface plate 9 in two, I"gre'atly increase the eflicienoy of the magnet 6, for the poles 7 and 8 induce magnetic poles on the two sides of the slot. The slot compels the lines of force to spread through the 'adjoining airg and'as thetype extends from one of these poles to the other, the lines of force will pass thrOugh the typeand tend to draw itdoWn-"against these poles.

' Thse-purposeof the filler'or plug 16 is to prevent any possibility of the type f-al ling "ousflush supporting 'sur ace for the t e enabling the type tof-be yp plate. V i

y The surface plate shouldhemade of=tool face. In *hardening the plate,- wh n the proper color is drawn, thep l-ate shouldbe of any solder Which' may be spilled accidentally upon it during'solderiiug operations. Special attention" is K called to the curved guidebar 22 which enables: the spring to be to be attathed to the which is'beingsoldered.

when'the is'egment is in -position orrthe rest 20, and the typebar'inplace in the type occupies the 's'ame p'ositiori in respect to the segment that the forWar'dface of-the -platen does 'when"the stglneiit' is secured in the machine.
